mirg_min_time (ul_mirg)

	status.i4.v = mirg_min_time(timev.r4.r, mi_reset.i4.v, file_num.i4.v)

	This routine returns the minimum time to be found in the ramp table
	associated with the given reset event.

	timev		The minimum time.
	mi_reset	A Main Injector reset event
	file_num	Specifies the file to use as the data source
			(Use MIRG_ACTIVE_FILE to specify the active file.)

	This function returns ACNET status values as follows:

	CBS_OK			Success
	CLIB_INVARG		The ramp table contains no data.
	SQL_xxx			Database error

	Note: This function is mainly included for completeness.  It would be
	an unusual table that returned anything other than zero.

	This function requires the following include files:

	ul_mirg_h:mirg_h, acnet_errors_h, tclk_events_h

	Related functions:

	mirg_max_energy, mirg_min_energy, mirg_max_time
	mirg_cnv_energy_time, mirg_cnv_time_energy

	C usage:

	int	status;
	float	timev;
	int	reset_event = EVENT_MI_RESET_REV_INJ;
	int	file_num = MIRG_ACTIVE_FILE;

	status = mirg_min_time(&timev, reset_event, file_num);
